To Whom it May Concern,

We have tested HEAT$AVR in our public pool and obtained a saving of 17% in our pool heating cost. Our customers do not notice the presence of HEAT$AVR. Furthermore, it has no effect on our filter or automatic chlorine systems. Staff find it easy to apply. We will continue to use this product at our facility.
